changes/1324-fetch-from-v3-not-v2

@@ -1,5 +0,0 @@
-  o Major bugfixes:
-    - Directory mirrors were fetching relay descriptors only from v2
-      directory authorities, rather than v3 authorities like they should.
-      Only 2 v2 authorities remain (compared to 7 v3 authorities), leading
-      to a serious bottleneck. Bugfix on 0.2.0.9-alpha. Fixes bug 1324.

changes/close_begindir_circs

@@ -1,7 +0,0 @@
-  o Major bugfixes:
-    - Relays now close idle circuits early if it looks like they were
-      intended for directory fetches. Such circuits are unlikely to
-      be re-used, and tens of thousands of them were piling up at the
-      fast relays, causing the relays to run out of sockets and memory.
-      Bugfix on 0.2.0.22-rc (where clients started tunneling their
-      directory fetches over TLS).

changes/close_idle_conns_faster

@@ -1,6 +0,0 @@
-  o Major bugfixes:
-    - Make relays more aggressive about closing TLS connections that
-      have no circuits on them. Tens of thousands of them were piling
-      up at the fast relays, causing the relays to run out of sockets
-      and memory. Bugfix on 0.2.0.22-rc (where clients started tunneling
-      their directory fetches over TLS).

changes/kill_clique_mode

@@ -1,4 +0,0 @@
-  o Minor features:
-    - Finally get rid of the deprecated and now harmful notion of
-      "clique mode", where directory authorities maintain TLS connections
-      to every other relay.

changes/use_ssl_option_everywhere

@@ -1,5 +0,0 @@
-  o Major bugfixes:
-    - Fix SSL renegotiation behavior on OpenSSL versions that claim to
-      be earlier than 0.9.8m, but which have in reality backported huge
-      swaths of 0.9.8m or 0.9.8n renegotiation behavior.  Possibly fix
-      for some cases of bug 1346.

changes/weasel-testuite-thread-fixes

@@ -1,8 +0,0 @@
-  o Minor bugfixes:
-    - Testsuite:  In the util/threads test no longer free the test_mutex
-      before all worker threads have finished.
-    - Testsuite:  The master thread could starve the worker threads quite
-      badly on certain systems, causing them to run only partially in
-      the allowed window.  This resulted in test failures.  Now the master
-      thread sleeps occasionally for a few microseconds while the two
-      worker-threads compete for the mutex.
